It’s very much worth testing the price of your app or service, but also worth trying to avoid having too many different prices visible to potential customers at the same time when you’re running different tests and segmented offers.

Here are 8 examples of different prices for FT.com subscription, all found within a couple of minutes searching Google for ‘ft subscription price’, ‘ft.com subscription offer’, etc.

There you go – eight prices – without even taking into account ‘monthly’ vs ‘annual’ rates.

I wonder whether this increases or decreases their results, and whether they’ve taken the “people who see multiple prices” effect into account in their testing.
